"I've never used my head for -THAT-!"

Appearance Body Type & Posture: Pumpy has a very imposing, broad-shouldered, and muscular build. His posture is stiff and formal, standing up straight with a rigid, almost military bearing.

The "Head": Instead of a human head, he has a dark, hollow collar area from which a small, flickering yellow flame emerges, acting as his "head." He is literally a dullahan or a spirit whose head is a flame.

Clothing: He dresses in an impeccably formal, somewhat Victorian style. He wears a crisp white dress shirt with a high, ruffled collar, a dark burgundy waistcoat (with gold buttons and a white tie string), and a heavy black cloak with a stiff, high collar that frames his fiery neck. He also wears dark gloves.

The Jack-o'-lantern: is what seems to be his actual head, capable of changing expressions and being freely removed from his neck and carried around comfortably.

His ghostly flame also works as an emotional indicator:

When calm: it burns steadily, almost like a candle in a sheltered room.

When embarrassed: it flickers rapidly or shrinks to a tiny, nervous tongue of fire.

When angry: it rises higher and becomes brighter, perhaps turning a more intense orange or crimson.

When genuinely frightened: it might sputter and momentarily go out, leaving him standing in awkward darkness.

When pleased: it burns warmly and steadily, betraying his happiness before he can conceal it.

Personality Heavily german: has a distinctive, deep but warm German accent and often uses German words, although knows English just as good.

Easily Flustered (Secretly): Despite his intimidating size and serious demeanor, he is easily embarrassed or shocked when people point out the absurdity of his situation. He is likely very socially awkward due to his nature and prone to overreacting internally while trying to maintain a stoic exterior.

Gentle & Protective: The way he holds his own head/the jack-o'-lantern—gently with both gloved hands, almost like a baby or a beloved pet—shows a surprisingly soft, nurturing side. He treats the pumpkin with great care, contrasting heavily with his terrifying, monstrous appearance.

In summary: He is a "gentle giant" monster—terrifying to look at and highly formal in his mannerisms, but utterly clueless in social situations and secretly a nervous wreck who finds comfort in cradling a festive gourd.
